About my home project (source are open in my github):

I am developing an online store for my girlfriend using cutting-edge technologies, just as hobby and self-improving. For the website, I'm utilizing Next.js and React, while Angular powers the admin panel. The backend for both the website and admin panel is built with Nest.js, all written in TypeScript. The project employs MongoDB and Redis as the database solutions.

Feel free to explore the code! Repositories located in my profile with prefix “shop-*”.

ACHIEVEMENTS

• Developed and implemented a commercial project with radio-frequency monitoring, which allows analyzing radio air and transmitting data in real time through various communication channels. Within the framework of the project, success was achieved due to the study of the features of radio receivers and the invention of ways of their direction finding and analysis.
  

• Responsible for finding an alternative to the GoogleMaps API. For this purpose, our own geo-coding was constructed based on OpenStreetMap (Nominatim), LibPostal and ElasticSearch. It is possible to create records linked to addresses/coordinates and perform a variety of searches on them with convenient autocomplete. The backend was based on Java, Spring (Data), MapStruct, Lombok and other technologies.
  

• Developed drones with autonomous landing based on visual landmarks, despite the fact that I had no experience with drones before. Over the course of a month, together with a colleague, I developed my own wrapper for ArduPilot (MavLink) on NodeJS (TypeScript), and made changes to the OpenCV library for my own needs.
  

• Assisted on a volunteer basis in a large Java open source project, helping to recreate and bring up the related infrastructure in AWS and making changes to the Android client.
